done at john hopkins university by watson and rayner on a 9 month old male
controlled observation (not a case study or experiment) done in a well lit dark room
5 stages such as establishing a conditioned emotional response
procedure
emotional test = was he already scared? will noise scare him?
start to condition = 2x joint stimulation = hammer against steel bar = wooden blocks as control object
any fear yet? embed via 5x joint stimulations
is it generalisable to other furry things = rabbit, dog, cotton wool, watsons hair
still scared in different setting = large lecture hall
still scared after some time? = one month later
findings
no initial fear of white rat
cried, head in hands when joint stimulation occurred
fear of white rat became conditioned
played happily with wooden blocks
less extreme fear of rabbit and fur coat but no fear of watsons hair or cotton wool
fear remained after a month but was less severe
conclusions
phobias are conditioned emotional responses
fears last longer for those constitutionally inferior = unstable
fears can be generalised to similar objects
unlike freuds belief that phobias are due to childhood traumas
lacks population validity = one ppt = male baby = cannot be generalised
lacks ecological validity = lab experiment = done in 'well lit dark room' = cant be generalised
standardised procedures = 5 stages eg. condition emotional response = can be checked for consistency = high external reliability
alternative evidence = freud believes phobias are caused by unconscious conflicts = little hans fear of dad shouting to fear of horses= contradicts watson and raynor
potential harm = no debrief or therapy given after = unethical = but said they offered but was denied and argued no more harm than every day life
invalid consent = vunlrable 9 month baby = cant understand information given = unethical
health implications = help treat phobias in new ways and counter condition them eg via systematic desensitisation = helps individuals
education implications = le francois showed conditioning improved student performance by using positive stimuli and reducing negative = better economy
